To n/ZZ whom. it muy concern/:

Be it known that LWILLIAM J. RUEF, a citi- Zen of the United States,residing in Quincy,

in the county of Adams and State of Illinois, have invented certain newand useful Improvements in Pasteurizers, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

My present invention relates to a machine for pasteurizing beer, &c.,and belongs to the same class of machines as those shown andone of thebottle-containing baskets and its drain-pipe. Fig.rIV is a sectiontakenon line IV IV, Fig. III. Fig. V is a horizontal` section taken on line VV, Fig. III. Fig.v VI is a detail section showing part of theattemperating and cooling' tank and its supply-pipe. Fig. VII is adetail top view showing a modiiication. on line VIII VIII, Fig.- VII.Fig. IX is a section taken on line IX IX, Fig. VIII. Fig. X is a sectionshowing the regulator; Fig. XI is a section showing one of thediaphragmvalves. Fig. XII'is a view similar to Fig. XI, showinganotherof the diaphragm-valves.

Referring to the drawings, 1 represents a tank for holding theattemperating and cooling water, and 2 is a tank for holding water ofmaximum temperature. A Fitting over these tanks and extending into thelatter is a housing or hood 3, thereby forming a leg or space 4in whichthe beer is attemperated, a leg or space 5, in which the beer is heatedto and for a suiiicient length of time retained at a maximumtemperature, and a leg or space 6, in which the beer is cooled. Thebottles of beer are conducted through these legs by means of a carriercomposed of endless chains Fig.`VIII is avertical section taken .drivenby any suitable form of motor (not shown) connected up to the shaft ofone of the sprocket-wheels 8. Communicating with Vthe tank 1 is a rotarypump 10, from which.

extends a pipe 11, having a branch 12 for dischargingattemperating-water into the baskets 9 in advance of the introduction ofthe water of maximum temperature and a branch 13 for dischargingcooling-water into the baskets after the bottles have been submitted tothe actionof the water of maximum temperature. In the pipe 12 is adiaphragm-valve 14, (see Fig. XL) such as is shown in my Patent No. 701,622, dated June 3', 1902. The air-supply pipe 15 of the diaphragm-valvecommunicates with a regulator 16, located in the tank 1. The regulatoris shown in Fig. X and consists of a cylinder 17, secured to one wall ofthe tank 1 and having a tube- 18, that extends into the tank. Within thetube 18 is a thermostatic bar or rod 19, the inner end of which is madefast to the end of the tube 18. In the outer end of the cylinder, 17 isfitted a plug 20, into which is tapped a stem 21, having a port 22, thatcommunicates with the pipe 15. The inner end of the stem 21 forms theseat for a valve 23 on the outerend of the thermostatic rod 19.

24 is a compressed-air pipe tapped into the plug 20 and whichcommunicates with the interior of the cylinder 17.

When the temperature in the tank 1 falls below a given point-say 90oFahrenheit-.- the bar 19 will contract and open the valve 23. Compressedair will then pass through the pipe 24, which is connected to a suitablecompressed-air tank, (not shown,) through the stem 21, and through thepipe 15 to the diaphragm-valve 14, thus causing the valve to be closedand shutting ofi the 110W of' water from4 the pump 10through a pipe 12into the baskets 9. When the temperature of the water in the tank 1rises above the desired temperature, the valve 23 closes again, thuspermitting the How or' water through the valve 14 and pipe 12 into'thebaskets 9. As the baskets become nearly filled with water they overiiowback into the tank 1-that is, so long as they are passing through theleg 4. This overow is from basket to basket and is permitted by means ofa double-legged pipe, (shown in Figs. III and IV,) and which consists ofa leg 33, communicating at bottom with the basket with which it ispivotally connectedy and at top with a leg 33, having adischarge-opening 37, that terminates beneath the basket, so as todirect the water into the basket beneath.

28 represents a rotary pump communicating with the tank 2 and from whicha pipe 29 extends to the top ot' the machine, where it is provided withbranches 30, having nozzles 31 for discharging hot water into thebaskets. The left-hand nozzle 31 is located in the upper part of the leg4, and this nozzle is provided with adiaphragm-valve 32, correspondingto the valve 14, except that it is held open by the compressedairpressure instead of being closed by the compressed-air pressure, so thatwhen the valve-14 is closed the valve ,32 is open, and vice versa, theresult being that when Athe water in the tank 1 falls below the desiredtemperature the valve 32 will be opened and hot water will pass throughthe baskets in the leg 4 into the tank 1, and thus restore thetemperature in the tank. As soon as the water rises above the desiredtemperature again the valve 32 will be closed and the valve 14 opened,and thus the cooling of the water caused by attemperating the cold beeris constantly counteracted by hot water passing from the tank 2 throughthe diaphragm-valve 32, the result being that the water in the tank l ismaintained at approximately a uniform temperature at all times.

As the carrier is passing through the leg 5 the beer is submitted to theaction oi' the water of maximum temperature which overiiows from thebaskets through the conduits 33 33a back into the tank 2, where it ismaintained at the maximum temperature in any suitable way-as, Jforinstance, by means or' a steam-jet 60, (see Fig. II,) located in a pipe61, that connects the two ends of the tank together. In the pipe 62 ot'the jet-pump is a diaphragm-valve 63, corresponding to the valve 14, andconnecting with the diaphragmvalve is a regulator 54, corresponding tothe regulator 16. When the water falls beneath the point desired-say148C Fahrenheit-the regulator 64 will open the valve 63, admitting steamto the tank through the pipe 61. As the carrier is passing up throughthe leg 6 the beer is submitted to the action of coolingwater depositedin the baskets through the pipe 13, which, as stated, communicates withthe pump 10, that is located in the tank l,

and the bottles are thus gradually cooled down before being exposed tothe atmosphere. As the baskets leave the top ol the leg 6 the watercommences draining therefrom into the baskets beneath, this beingell'ected through means of the swiveled double-legged pipes 33. (SeeFigs. III and IV.) These pipes are connected to the lower portions olthe baskets, as shown in Figs. III and V, and they are slowly turnedinto a horizontal position by coming against a pin 36. (See Fig. I.) Asthey are turned the water flows from their lower extended ends 37 and isdischarged into the baskets beneath and iinally back into the tank 2.rl`he bottles are thus gradually cooled down as they move upwardlythrough the leg 6. Then the carrier is moving downwardly from thesprocket-wheel that is located over the leg 6, the baskets are empty olwater, so that the beer can be removed about the poin t B. Beneath thispoint there is located another stationary pin 38, against which thepipes 33 impinge and are turned back to their upwardly-inclinedpositions, so that the baskets are ready to take and hold water againwhen they reach the point A.

Any loss of water in the tanks is restored through pipes 40, providedwith valves 4l, to which are connected lioats 42, located within thetanks. (See Figs. I 'and Vl.) \\"hen the water falls beneath the desiredlevel, the floats will by descending open the valves 41, thus permittinga flow ol water into the tanks from the pipes 40, which are connectedwith any suitable source ot' water-supply.

54 represents stationary rails tor guiding the endless chains of thecarrier where they are deiiected in the course oil their travel.

In Figs. VII, VIII, and IX, l have shown a niodiiication of thedouble-legged pipe 33 33, which consists in locating a iixcdwaterconduit at one end of the baskets, which conduit consists ot a leg'25, communicating with the lower part of the basket and at top with aleg 26, having a lower extension 27, that terminates beneath the basket.'lliis conduit permits the overiiow ot' the water from the basket, andto discharge the water from the baskets (which in the other form iseilected by the turning of the pipe 33 33, as described) I employ avalve 27, which is normally held to its seat by a spring 27"'. The stemot the valve projects some distance beyond the basket and is adapted tocome against a suitable stationary pin to etliect the opening ol theValve when the baskets reach the top ol the leg 6. I/Vith a machine thusconstructed a very small tank may be utilized, inasmuch as theattemperating and the cooling et the beer is eifected without the useoi. a l'ank to hold the water through which the carrier is passing atthe time that the atten'iperating and cooling processes are beingcarried on.
